Pneumatic Relay Valve

Description: The Series 62 Constant-Differential Relays serve as air-flow controllers maintaining a constant air purge for ech setting of an integral needle valve. By maintaining a constant-differential pressure drop across a built-in needle valve (for any flow setting up to 2.1 cu. ft. of air per hour

• Type: Ratio Relay
• Body Material: Aluminum, Stainless Steel, Other

Description: is adjustable from 1 to 100 psi with a simple screw stem. The Mite 70 can also be tripped on demand from a separate remote signal. Use the Mite 70 to open safety valves in emergency situations, trigger an alarm while locking up a valve or actuate diaphragm motor valves, air cylinders or other pneumatic

• Type: Snap Acting Relay

Description: Low Activation Force < 2.7 Oz. @ 90 PSI. Produces a Permanent Bleed at Its Input Port Positive or Negative Output Relays Works with Relays Listed Below

• Actuation: Pneumatic

Description: Applications Control valves and actuators Petro-chemical plants Grain handling Waste treatment Hazardous waste handing Power generating Paint facilities Description CX switches are built especially for outdoor use in hazardous atmospheres. These enclosures are constructed

Description: The Type-650 positive bias relay is a signal operated regu lator that provides an output pressure that is the sum of the input signal pressure plus a preset bias. The unit allows flow capaci ties up to 50 SCFM with minimal pressure drop. An aspirator tube at the output maintains the set pressure

• Type: Bias Relay
• Body Material: Aluminum

Description: The QB3 is a complete electronic pressure regulator package consisting of two feed and bleed solenoid valves, a control circuit, a pressure transducer, an integral air pilot operated volume booster, and a rugged IP65 housing. The pressure transducer is connected directly to the control pressure so

• Type: Volume Booster
• Body Material: Aluminum

Description: The Type 6000 Volume Booster is a one-to-one signal to output relay that, when used with a positioner/actuator, is designed to increase the stroking speed of control valves. A large input signal change to the volume booster delivers high volume, fast action throttling control. An integral bypass

Description: Kelly Pneumatics, Inc. offers a Driver Board for its Proportional Valve product line. This driver board converts an input signal proportionally to an output current, driving the attached valve appropriately with excellent resolution. Can also be applied to other electronic applications in need

Description: Honeywell RP670B1017 Pneumatic Switching Relay: Pneumatic switching relays block, divert, or bleed pneumatic air lines when pilot pressure is changed from one specific value to another. Commonly applied in Day-Night, Summer-Winter, Start-Stop, On-Off-Auto and other multiple condition systems

Description: Used extensively for increased flow capacity or remote pressure control applications, the Type 650 positive bias relay is a signal operated regulator that provides an output pressure that is the sum of the input signal pressure plus an adjustable preset bias. The unit allows flow capacities up
